Geofund Insurance Receipt

Green Rock Energy Limited (ASX: “GRK”), a geothermal energy company, is pleased to advise the receipt of A$1.3 million geological risk insurance payment from the Geothermal Energy Development Program, or Geofund. The refund to the Company represents the major costs incurred by the Company with preparation and production testing the Othaháza 3 and Othaháza 5 wells in early 2007.

The Geofund is funded by the Global Environment Facility Trust Fund and implemented jointly by the World Bank and the IFC.

Hungary has enormous potential for the extraction and development of geothermal energy, given both the significant resource and a fiscal regime that encourages geothermal developments. With the wealth of existing drilling and seismic data at its disposal, Green Rock Energy, in joint venture with the Hungarian oil and gas company, MOL and the Icelandic geothermal consulting and development company, Enex hf, is finalising the location of the next Hungarian geothermal projects in areas identified by a joint technical team with the objective of production testing later this year.
